Environmental Consequences and Profitability Analysis of Dry Season Small Scale Irrigation Farming in the Bawku West District of the Upper East Region, Ghana

ABSTRACT  This study assessed dry season farming profitability and examines farming practices and their influence on the environment. Dry season farming practices identified from the literature were irrigation practices, land preparation, tillage practices and use of agrochemicals. A cross sectional design was adopted as quantitative data was collected from respondents. Five (5) communities along the White Volta River in the Bawku West District were purposively selected based on their p...

An Overview of Rattan Distribution in Four States in South-South Part of Nigeria

Abstract: Rattan, a non-timber resource in Nigeria’s South-South forests remains largely unexplored. To create schedule for unlocking its potentials, this study investigates its availability, distribution and current utilization pattern in Akwa-Ibom, Bayelsa, Cross-rivers and Rivers States in Nigeria. Information was collected using structured questionnaire and on-the-spot-assessment while data was analyzed using simple statistical tools. The four states has rattan in abundance but unevenl...

Hatchery Production Optimisation Using Monte Carlo Approach

ABSTRACT Optimization of hatchery production processes was carried out using the Monte Carlo method. In the economics. of engineering decisions with the objective of the investor identifying an optimum solution. an investor chooses his or her optimal solution from the set of scenarios that offer maximum expected return for varying levels of risk. Outcomes associated with these random numbers are then analysed to determine the likely results and the associated risks. Taking a major day old h...

Development and Evaluation of Pineapple (Ananas comosus [L.] Merr.) Pomace Based Extruder

ABSTRACT In large scale juice processing, about 65% of the pineapple is extracted as juice, while the remaining 35% is the by-product called pineapple pomace. Pomace generated from juice processing constitutes a disposal problem and environmental pollution and there is no processing equipment designed in addressing this problem through the utilisation of this byproduct. This study was designed to develop a mash extruder for pineapple pomace based flour. Pineapple pomace was analysed for its...

STRATEGIC BASELINE STUDY OF AJASSE IPO WATERSHED CATCHEMENT AREA

Presently, Nigeria is among the nations that are technically unable to meet their food supply needs from rain-fed production at a low level of inputs and appear likely to remain so even at intermediate levels of inputs at some point’s time between 2000 and 2025 (FAO 2002). For the rural areas of semi-arid Northern Nigeria, which experiences significant climatic and anthropogenic changes that have exacerbated food insecurity in the region, floodplain agriculture is critical to the survival...

Assessing Growth Rate of Jatropha Plant (Height and Diameter) Under Different Method of Propagation in Nyankpala In Northern Region Ghana

ABSTRACT The study was carried out at Nyankpala in the Northern region of Ghana from November 2012 to April 2013 to investigate the growth rate of Jatropha plant under two methods of propagation (seeds and cuttings) that best support the growth of the plant. Data on the survival rate, height and diameter were collected and other data were obtained through observation. Each of the plantation was divide into nine (9) plots and five plots were selected randomly for the studies. Each of the plant...

DISCUSSION ON THE CROP WATER REQUIREMENT, PERIOD OF PLANTING, DAYS TO HARVEST (DEVELOPMENTAL STAGE) AND AREAS PLANTED OF THE FOLLOWING VEGETABLE (FRUIT) CROPS: TOMATO, ONION, OKRA, PEPPER

One of the most critical inputs to vegetable (fruits) production in semi-arid areas, dry season farming and nursery establishment is water. During the dry season or off season, the source of water for vegetable growing is from irrigation while in the wet season, rainfall is the source of water. Young vegetable seedlings in the nursery or in the field should be watered in the early morning or in the evening. Watering should be done before transplanting particularly in the evening. Over-wa...

A Review of Soil Dynamics in Traction Studies

As the world population increases more than ever before and increasing demand on food, feed and fiber, and security, the number of off-the-road vehicles is rapidly increasing for agriculture, forestry, military, mining and construction industries. Many researchers have studied and still investigating traction as it relates off-road vehicles and publications abound especially from developed countries of Europe, America and others. In our generation scientists are trying to put robotic vehicles...

Impact of Petroleum Industrial Degradation on the Yield of Agricultural Produce

Abstract The study focused on the impact of petroleum industrial degradation on agricultural produce in Ilaje Local Government of Ondo state. Four research questions were developed in conformity with the purpose of the study. The study adopted survey research design. Questionnaires were administered to elicit information on crop productivity, livestock productivity, forest and aquatic organisms and therefore the strategies to cope with the impact of petroleum industrial degradation. A total o...

EFFECT OF SALINITY ON THE PHYSIOLOGICAL BEHAVIOR OF THE OLIVE TREE (VARIETY SIGOISE)

Salinity is a major problem directly affecting the ecological balance and the development of agriculture in the Mediterranean basin, particularly North Africa. This phenomenon is considered as the most important abiotic factor limiting crops growth and productivity, degrading and polluting soils in arid and semi-arid. In order to study the influence of salinity, on the physiological parameters and to assess the potential of adaptation of the olive tree in a saline environment, three parcels c...

Evaluation of yield characteristics cum determinant factors in earth mound method of charcoal production using billet of Acacia nilotica

ABSTRACT Tree residues are generated in large quantity in our environment. Nowadays, adding value to these residues could make them become item of economic importance. The aim of this study is to adapt a traditional method of charcoal production (Earth Mound) in order to add value to the tree residues generated in University of Ibadan with a view to enhance the benefit derived from them. The billets of Acacia nilotica were converted from both wet and dry wood samples. The billets were t...

Charcoal Yield from Urban-Tree Residues Generated in University of Ibadan, Nigeria using Earth Mound Method

Abstract The cost of managing ornamental and naturally growing trees in the University of Ibadan, Nigeria, is becoming challenging. Adding value to the residues from these trees with a view to enhance its economic value will minimize the management cost. This study adapted Earth Mound method of charcoal production to add value to tree residues generated in the University of Ibadan to enhance its economic value. Mixed residues of Acacia nilotica (Acacia), Albizia zygia (Ayunre) and Melicia ex...

Dimensional Stability and Mechanical Properties of Wood Plastic CompositesProduced from Sawdust of Anogeissus leiocarpus (Ayin) with RecycledPolyethylene Teraphthalate (PET) Chips

ABSTRACT Wood Plastic Composite panels were produced using a locally fabricated extruding machine at a temperature of about 170°C-200°C. the Sawdust of Anogeissus leiocarpus(Ayin) and Recycled Polyethylene Teraphthalate (PET) Chips were mixed in the ratio 1:1 to 1:5 and densities of 770.58 kg/mm3, 888.65 kg/mm3, 1,114.71 kg/mm3, 1,117.58 and 1, 141.84 kg/mm3 respectively. The quantity of recycled polyethylene teraphthalate (PET) Chips and sawdust used in the panels production were later...
